Packages tested:
kernel-3.10.0-799.el7.x86_64
qemu-kvm-1.5.3-149.el7
Test steps:
1. Create image with large size
# qemu-img create -f qcow2 test_large.qcow2 30720T
Formatting 'test_large.qcow2', fmt=qcow2 size=33776997205278720 encryption=off cluster_size=65536 lazy_refcounts=off
qemu-img: test_large.qcow2: The image size is too large for file format 'qcow2' (try using a larger cluster size)
# qemu-img info test_large.qcow2
